How to: Manipulate a Table's Row Groups through the RowGroups Property

This example demonstrates some of the more common operations that can be performed on a table's row groups through the RowGroups property.

Example

The following example creates a new table and then uses the Add method to add columns to the table's RowGroups collection.

            Dim tbl As New Table()
            Dim rowGroupsToAdd As Integer = 4
            For x As Integer = 0 To rowGroupsToAdd - 1
                tbl.RowGroups.Add(New TableRowGroup())
            Next x

Table tbl = new Table();
int rowGroupsToAdd = 4;
for (int x = 0; x < rowGroupsToAdd; x++)
    tbl.RowGroups.Add(new TableRowGroup());

The following example inserts a new TableRowGroup. The new column is inserted at index position 0, making it the new first row group in the table.

            tbl.RowGroups.Insert(0, New TableRowGroup())

tbl.RowGroups.Insert(0, new TableRowGroup());

The following example adds several rows to a particular TableRowGroup (specified by index) in the table.

                Dim rowsToAdd As Integer = 10
                For x As Integer = 0 To rowsToAdd - 1
                    tbl.RowGroups(0).Rows.Add(New TableRow())
                Next x

int rowsToAdd = 10;
for (int x = 0; x < rowsToAdd; x++)
    tbl.RowGroups[0].Rows.Add(new TableRow());

The following example accesses some arbitrary properties on rows in the first row group in the table.

            ' Alias the working TableRowGroup for ease in referencing.
            Dim trg As TableRowGroup = tbl.RowGroups(0)
            trg.Rows(0).Background = Brushes.CornflowerBlue
            trg.Rows(1).FontSize = 24
            trg.Rows(2).ToolTip = "This row's tooltip"

// Alias the working TableRowGroup for ease in referencing.
TableRowGroup trg = tbl.RowGroups[0];
trg.Rows[0].Background = Brushes.CornflowerBlue;
trg.Rows[1].FontSize = 24;
trg.Rows[2].ToolTip = "This row's tooltip";

The following example adds several cells to a particular TableRow (specified by index) in the table.

                Dim cellsToAdd As Integer = 10
                For x As Integer = 0 To cellsToAdd - 1
                    tbl.RowGroups(0).Rows(0).Cells.Add(New TableCell(New Paragraph(New Run("Cell " & (x + 1)))))
                Next x

int cellsToAdd = 10;
for (int x = 0; x < cellsToAdd; x++)
    tbl.RowGroups[0].Rows[0].Cells.Add(new TableCell(new Paragraph(new Run("Cell " + (x + 1)))));

The following example access some arbitrary methods and properties on cells in the first row in the first row group.

            ' Alias the working for for ease in referencing.
            Dim row As TableRow = tbl.RowGroups(0).Rows(0)
            row.Cells(0).Background = Brushes.PapayaWhip
            row.Cells(1).FontStyle = FontStyles.Italic
            ' This call clears all of the content from this cell.
            row.Cells(2).Blocks.Clear()

// Alias the working for for ease in referencing.
TableRow row = tbl.RowGroups[0].Rows[0];
row.Cells[0].Background = Brushes.PapayaWhip;
row.Cells[1].FontStyle = FontStyles.Italic;
// This call clears all of the content from this cell.
row.Cells[2].Blocks.Clear();

The following example returns the number of TableRowGroup elements hosted by the table.

            Dim rowGroups As Integer = tbl.RowGroups.Count

int rowGroups = tbl.RowGroups.Count;

The following example removes a particular row group by reference.

            tbl.RowGroups.Remove(tbl.RowGroups(0))

tbl.RowGroups.Remove(tbl.RowGroups[0]);

The following example removes a particular row group by index.

            tbl.RowGroups.RemoveAt(0)

tbl.RowGroups.RemoveAt(0);

The following example removes all row groups from the table's row groups collection.

            tbl.RowGroups.Clear()

tbl.RowGroups.Clear();
